Задача. Пусть 𝐾 и 𝐼 — середины сторон 𝑁𝑂 и 𝑂𝑊 выпуклого четырехугольника 𝑆𝑁𝑂𝑊. Максимизируйте площадь 𝑆𝑁𝑂𝑊, если длина ломаной 𝑆𝐾𝐼 (𝑆𝐾 + 𝑆𝐼) равна единице.

During the operations, Sebi officials seized various records and documents, including 34 mobile phones, six laptops, four desktops, four tablets, two hard drive disks and one pen drive from the custody of these persons. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. Individual messages can be fully encrypted. But the user has to turn on that function.

Meanwhile, a completely redesigned attachment menu appears when sending multiple photos or vides. Users can tap "X selected" (X being the number of items) at the top of the panel to preview how the album will look in the chat when it's sent, as well as rearrange or remove selected media.
